        if (File.Exists(paraFile))
            File.Delete(paraFile);
        using (FileStream fs = new FileStream(paraFile, FileMode.Create))
        {
            //fs.Seek(0, SeekOrigin.Begin);
            //fs.SetLength(0);
            using (StreamWriter sw = new StreamWriter(fs))
            {
                //声明数据流文件写入方法
                sw.WriteLine(markLineOfRobotReason);
                sw.WriteLine("");
                foreach (string reason in robotRegisterReasons)
                    sw.WriteLine(reason);
                sw.WriteLine("");
                sw.WriteLine(markLineOfHumanReason);
                sw.WriteLine("");
                foreach (string reason in humanRegisterReasons)
                    sw.WriteLine(reason);
                test++;
                sw.WriteLine("");
                sw.Write("第" + test + "次写末尾参数");
                sw.WriteLine(markLineOfExecRate);
                sw.WriteLine("");
                sw.WriteLine(comboBox1.SelectedItem.ToString());
                sw.WriteLine("");
                sw.WriteLine(markLineOfIfShown);
                sw.WriteLine("");
                sw.WriteLine(checkBox1.Checked);
            }
        }

result is like this:
